Temperance Brennan has a mystifying new case in this eighth novel from New York Times bestselling author and world-class forensic anthropologist Kathy Reichs. Tempe is called in to interpret the wounds of a man who was shot in the head, but while she tries to make sense of the fracture patterning, an unknown man slips her a photograph of a skeleton, telling her it holds the answer to the victim's death.

The freezing Montreal winter turns even colder when blue-eyed cop Andrew Ryan is too busy mounting a sting operation and squiring a fetching youngster around to pay much attention to the forensic anthropologist who's his sometime squeeze. Temperance Brennan can't even turn to her chum Anne for much solace because Anne, on a leave of absence from her marriage, is needy herself. Work is no consolation either, since Tempe is facing a riddle she can't solve. 

It's a summer of record-breaking heat in Charlotte, North Carolina and Dr Temperance Brennan is looking forward to her first vacation in years. She's almost out the door when the bones start appearing. First there's the newborn skeleton found in a wood stove. Who put the baby there?

As a forensic anthropologist for the state, she serves on the region's disaster response team. The task that confronts her is a sad and sickening one. Putting normal life on hold, she and her colleagues must painstakingly identify the victims...
